Made a mistake in the post above but couldn't edit post as apparently you have to do it within 7minutes!

Please ignore the above. Here is the post again with my edits to it:

If you want to add a background image behind the main content box aka page,
then add this to Your Custom template css stylesheet:

body{ margin: 0; padding: 0; text-align: center; font-family: tahoma, verdana, arial, helvetica, sans-serif; font-size: 12px; color: #000000;background: #E0E0E0 url('../images/your image.jpg'); }


If you mean that you want the whole page to display the image and you don't want a "page" to be displayed on top of the image,then you can make the "page" transparent by adjusting the following in your Custom template css stylesheet:

#mainWrapper{ background:here you can try to use the word transparent}

Or else you can use the following standard css codes for transparency:

selector {
filter: alpha(opacity=50); /* internet explorer */
-khtml-opacity: 0.5; /* khtml, old safari */
-moz-opacity: 0.5; /* mozilla, netscape */
opacity: 0.5; /* fx, safari, opera */
}
